I'm sorry, I phrased that so unclearly.
That's what I meant to say: It works just fine in a shell with any
combination of arguments/options I tried. No problem so far.

My command definitions:
----snip----
define command {
  command_name    check_ircd
  command_line    /usr/lib/nagios/plugins/check_ircd '$HOSTADDRESS$'
$ARG1$
}

define command {
  command_name    check_ircd_fail
  command_line    /usr/lib/nagios/plugins/check_ircd -H '$HOSTADDRESS$'
$ARG1$
}
----snap----

And this are the services using those commands:
----snip----
define service {
  host_name               localhost
  service_description     IRCd
  check_command           check_ircd!-p 1984
  use                     henk-stdsrv
  notification_interval   0
}

define service {
  host_name               localhost
  service_description     IRCd-fail
  check_command           check_ircd_fail!-p 1984
  use                     henk-stdsrv
  notification_interval   0
}
----snap----

The first one reports the service as OK:
IRCD ok - Current Local Users: 17

While the second says UNKNOWN:
Invalid warning threshold: -H

When i make the following change in both service definitions, both
report OK with the above mentioned message:
check_command           check_ircd!-p 1984 -w 55 -c 80

Note that all of those commands work just fine in a shell, just not in
nagios. But as i now tested only when the embedded perl interpreter is
used implicitly. So I guess this bug can be closed or perhaps
reassigned.

Sorry for the trouble.

Best regards

Hendrik
